provementsin Apparatus for Heating by' Catalysis, of which the following is a specification.

` This invention relates to catalytic heating apparatus, and consists broadly in the formation of projections on the radiating surface of the platinated asbestos principallyl in order to increase the heating area.

In the accompanying drawings,

Figure l shows the application of the invention to a heating apparatus placed on a known type of lamp b. Fig. 2 illustrates the invention applied to a heater with hori' zontal vapor supply. Fig. 3 illustrates the `invention applied to a smoothing iron. Re-

ferring to Fig. l, the cushion or carpet of asbestos a presents, on its upper surface bosses a1 or other designs, such as undulated or spindle-shaped embossing, of any arrangement and shape, for the purpose, on the one hand, of facilitating the'inflammation of the spirit vapors when the apparatus starts working and, on the other hand, ofV increasing the active radiating surface of the apparatus and consequently its'heating power. y

In this yarrangement the metal tube 0 passes through the carpet of asbestos at its base, and it contains, near its lower part,

. openings c1 to allow the evaporation and outlet of the spirit. One vof the bosses may be provided at the center of the catalyzing y carpet. .By raisin the wick'which passes inside the tube c, te latter may be brought into contact with the platinated asbestos, thus at once allowing the spirit to rise byv capillarity into the asbestos through the uncovered surface of said wick.- 'A light'may be applied to the said central boss, so as to bring the heater into activity.v At` the end of some minutes, the ame vwill be extin- IleSSeS.

.E Witnesses:

v guished of itself, the wick should then be lowered again. l y According to the arrangement of the apparatus, the tube e, instead of being vertivcal can also be horizontal, as shown in Fig.

2, in order to enable spirit to be supplied. Fig. 3 represents a boX-iron heated by catalysis. The necessary heat is supplied to it by a catalyzing carpet a, with bosses on the lower surface which, in a smoothing iron is the radiating surface. One or more perforations g1 in the mass of iron which forms the iron allow the air to feed oxygen to the carpet. The spirit reservoir b1 bein placed above, in order to present the liqui spirit from dropping on the catalysant which would stop the catalysis-a special device should be employed. This device consists in a tube la' secured to the reservoir b1 and containing a wick which descends down to k1 and rises in thebottom of the' reservoir up to h2; surrounding this 'first tube there is another z' of smaller diameter, closed at z'l and perforated at 2. yBetween the two tubes'carded asbestos serves as wick and sucks up by capillary attraction the spirit brought by the wick, which then evap-1 orates through the opening 2.

What we claim as our invention and desire to secure by Letters Patent ofthe United States is 1. In a catalytic heating apparatus, a catalytic pad so formed that the radiating surface is undulatory, and means for supplying inflammable vapor to said pad.

2. In a catalytic heating apparatus, a catalytic pad, thel radiating surface of which is formed with a plurality of bosses, and means for supplying inflammable vapor to said pad. Y n

In witness whereof we have signed this specification in the presence of two wit- RAMON CAMELL. LAURENT COCHE'I. JOSEPH GRITTE.
